Better support metabolites in `sawtooth`

Also, add more example code to make it easier to use
`one_box`, `sawtooth` and `pfm_degradation`.

However, for generating sawtooth curves with specified
output times, overlaying the output of several calls to
`mkinpredict` is probably still easier.

 ## version 0.6.5
 
+- Add a `one_box` method for `mkinmod` objects to facilitate generating `sawtooth` curves also for metabolites
+- R/pfm_degradation.R: Fix using an mkinmod model and add an SFO-SFO example
 - R/PEC_sw_drift.R: Support specifying units for distances and widths using the units package.
 - R/TOXSWA_cwa.R: Adapt to readr (>= 2.2.0) requiring to wrap literal input as used for reading .out files with I().
 - R/PEC_sw_drainage_UK.R: Create a function `drainage_date_UK` that does not only respect the beginning of the drainage period on 1 October, but also the end of the drainage period on 30 April, and use it for determining the degradation time. Applications early in the year before 1 May will now correctly be calculated without degradation time.
